L-抗坏血酸棕榈酸酯制备
1. 将64g棕榈酸置于加热滴液漏斗中,使其处于熔融状态;将200mI。二氯亚砜装入烧瓶中,加热使其蒸气通过导管进入装有瓷环填料的反应柱,与从柱子上部滴加的棕榈酸反应,未反应的二氯亚砜通过反应柱上部的支管冷凝后回到烧瓶;棕榈酸滴加完毕后反应30min,常压蒸馏除去少量二氯亚砜,减压蒸馏收集150~152℃(2~3kPa)馏分无色透明液体58.6g,产率86%(按棕榈酸计)。
2. 在烧瓶中加入26.5mL。二甲基甲酰胺,于0℃下通入HCl气体2g,然后加入9.69g结晶抗坏血酸和13.3mL。二氯甲烷,此时反应液澄清;在0℃下慢慢滴15.2mL,棕榈酰氯,滴加完毕后反应18h,再升温至20℃反应30min。将反应物加入到100mL。乙酸乙酯和200mL。水中搅拌洗涤2h,抽滤后用水(50mL×3)洗涤3次,50℃下真空干燥18h,得白色粉末17.5g,产率84.3%。
3.由棕榈酸氯化生成棕榈酰氯,然后与抗坏血酸酯化,经过滤、干燥得抗坏血酸棕榈酯。
